So it sounds like, not surprisingly, you get what you pay for. Will the Webra .50 last? Is it delicate? Although I obviously don't plan on burying the engine in the dirt, I'm definitely not the world's best pilot, so these issues matter a great deal to me. What I have noticed in higher end products, in general, is that the value decreases (sometimes significantly). I'm not afraid to spend the money for the Webra, but I'd like to think that I would get some serious life out of it (for example, racing tires on a car sure look cool and perform well, but they don't last very long). Has anyone rebuilt one of these things? Thanks for the input.
